After becoming the first plus-size model to land the cover of People magazine—and creating the popular #EffYourBeautyStandards hashtag to honor women of every shape and size—Tess Holliday has been an outspoken supporter of the body positivity movement. It should also come as no shock that when, during a recent Uber ride, a driver allegedly questioned Holliday's health because of her size, she blasted the driver for fat-shaming her and called out the company on social media.

"Hey Uber I don't pay more to use your 'black car' service to be told that there's no way I could possibly be healthy because I'm fat and then questioning it," Holliday wrote in an Instagram caption posted alongside a video of her recent ride.

In the clip the driver seems to be asking Holliday about her cholesterol levels, to which she responds, "My cholesterol is fine, yeah. I’m healthy."

Holliday went on to explain that after the incident—and the apparent criticism and shaming offered by her driver—she will no longer be using the car-sharing app.

"No one should have to tolerate this at any level of the services you offer," Holliday wrote. "I'm fat. I also have a fat wallet and will no longer be using your services. Ever."

Though it should go without saying, this is another reminder that shaming someone for their weight—or any aspect of their physical appearance—is never acceptable. Holliday's video included overlay text reading, "My driver who is fat is questioning if I'm healthy," which some followers felt was hypocritical. She offered a clarifying note to her Instagram comment, editing it to add: "Saying my driver is fat was obviously being used as a descriptor & not to insult him. Also I did not show his face or use his name when filming, it was to be able to show what I deal with daily & why this behavior is unacceptable from anyone." Maybe next time that driver will stick to commenting on the weather or traffic rather than the bodies of his passengers.

When asked to comment on Holliday's post, a spokesperson for Uber told Glamour, “We expect all riders and drivers to treat each other with respect as laid out in our community guidelines.”
